The UNEP methodology establishes a generic framework for thinking about and responding to the
problems of sea level rise and climate change.

The user goes through the following seven guiding steps:

Define the problem;

Select the method;

Test the method;

Select scenarios;

Assess the biogeophysical and socioeconomic impacts;

Assess the autonomous adjustments;

Evaluate adaptation strategies.

The last step is itself split into seven substeps. At each step, methods are suggested but the
choice is left up to the user.

Appropriate Use

This approach is useful in a range of situations, including subnational, or national level studies.
It could comprise the first study, or follow earlier studies such as those completed using the IPCC
Common Methodology.

The possibility of a quick screening assessment followed by a more detailed vulnerability
assessment has been suggested. Information gathered with this methodology can then be used as input
for future modeling.
